FREQUENTLY ASKED QUESTIONS
What areas do you service?
We’re proudly based on the Central Coast and do most of our work locally — from Gosford to Wamberal and everywhere in between. We also take on select projects in Sydney and Newcastle, depending on the job size and timeline.
How long does a second-storey addition take to complete?
Most second-storey additions are completed within 8–12 weeks, depending on the scope of the build and weather conditions. We pride ourselves on efficient project management and clear timelines, so you’re never left guessing.
Are you licensed and insured?
Absolutely. RJ Built Co is fully licensed and insured for residential carpentry and construction work. We meet all NSW building regulations and safety standards — your project is in experienced, capable hands.
Can you help with council approvals or planning?
Yes — we’re happy to work alongside your architect or engineer and can also refer you to our trusted professionals if you’re starting from scratch. While we don’t lodge plans directly, we’ll guide you through the process and ensure the build runs smoothly from approval to completion.
FOUNDERS NOTE
"I started RJ Built Co with a simple mindset — get the job done right, get it done fast, and back it up with a team you can trust."
My name’s Ryan James — I’m a Central Coast local, a qualified carpenter, and the proud owner of RJ Built Co.
I've tools for over a decade and built everything from high-end second-storey additions to decks that turn a backyard into the best room in the house. I’ve always believed in showing up on time, keeping things simple, and delivering the kind of work that speaks for itself — clean, sharp, and built to last.
RJ Built Co isn’t just me — it’s a crew of experienced, hard-working legends who take pride in their work and treat every home like it’s their own. We don’t cut corners. We don’t drag things out. We just show up and build.
